'Shake Weight is an infomercial fitness product that is a version of the classic dumbell that has been modified to shake vigorously. The lengthwise shaking motion that the Shake Weight produces has been mocked for resembling the motion made during male masturbation. The Shake Weight was created by the company Fitness IQ in July of 2009, and was marketed as a fitness tool to reduce female arm flab. According to the Shake Weight website, the motion that the dumbbell produces is called “Dynamic Intertia”: A commercial advertising the female Shake Weight was uploaded to YouTube on February 19th, 2010. It has received 2.1 million views as of August 2011.'
